HAT-PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 237,069, dated January25, 1861.

Application filed July 12, 1880. (No model.)

To all whom in? may concern Be it known that we, CHARLES TYRRELL andEDWARD KEARNs, of Norwalk, in the county of Fairfield and State ofConnecticut, have invented a new and useful Improvement in Hat-PressingMachines, of which the following is a specification.

The object of our invention is to provide for more accurate andconvenient adjustment and regulation of the pressure in machines forpressing hat-bodies.

Heretofore in such machines the die or block has been fitted upon afollower fitted for movement by a cam-lever to give the pressurerequired, the block being first adjusted; but in such machines the rangeof adjustment is limited, and considerable care is necessary to insureproper pressure.

We make use of an upright frame, the upper cross-rail of which carries afixed mold and supports by adjustable rods a lower crossrail that isfitted for movement upon the side bars of the frame. Between the upperand lower rail of the frame is a cross-head, fitted for movement bytoggle bars connected to the lower rail, and carrying the block or die,which is supported by a leg upon eccentrics or cams that are fitted formovement by a lever to raise the mold. The mold is first brought upbythe toggles, and the required pressure then given by the cam-lever.

The construction and operation will be described in detail withreference to the accompanying drawings, wherein Figure l is a frontelevation of the machine. Fig. 2 is a vertical transverse section 011line as a; of Fig. 1. Fig. 3 is a detail section on line y y of Fig. 1.

Similar letters of reference indicate corre sponding parts.

The frame, composed of side standards, a a, and top rail, 1), issupported on the floor or a suitable base.

At the lower ends of the standards a (t is placed a rail, 0, havingmortises in its ends that set over guides d, that are fixed upon the theinner sides'ofthe standards and supported from the top rail, 12, by rods0 c and nuts f f, so that the rail 0 may be adjusted to and from theupper rail.

Between the standards is fitted a head or follower, A, composed ofcross-bars g g and posts h h, secured together by the rods 9, the nutsof which are loose to allow raising of the upper bar g, as hereinafterdescribed. The lower bar 9 of head A and the rail 0 are connected bytoggle-bars t, which are suitably jointed to the rail and bar. The lowertoggle is jointed to the lugs of a casting, k, that is attached uponrail 0, which casting is also fitted with a cross-shaft, k, having anarm that connects, by a link, Z, with the joint-pin of thetoggle-levers. Upon this shaft k is also fitted an arm, m, by which theshaft may be turned to move the toggles, which arm is to be suitablyconnected for operation by hand or foot.

At the under side of the top rail, 1), is rigidly attached the mold andupon the top bar 9 of head A the die or block 0 rests, a lug on itsunder side entering a mortise of the bar. To the under side of this bar9 is attached a hanger, p, which is fitted in its lower .forked end witha lever, q, that is formed with a toothed cam which engages with a camor eccentric, r, that is hung in suitable bearings on the lower bar g.The die 0 consists of an outer shell of metal, containing a bedding, 8,of elastic material, that is sustained-upon an interior metal form, .9.The lower side of mold n is shaped to receive the block, and between theelastic bedding 3 and metal mold 0 the bat is pressed.

By operating the arm m to bend the togglebars 2' the head A is broughtdown, and space thereby given for placing the bat upon the die, and byreverse movement of arm m the toggles are straightened and the die andmold brought together, with the bat between them. The rail 0 is to beadjusted so that this movement of arm m shall bring the hat to the shaperequired, or nearly so, and further adjustment may be made, according tothe shape and size of block 0, by placing washers between block 0 andbar 9. After the head A is raised the pressure is to be given bypressing the camlever q down, which raises the upper bar, g, and die 0.Great pressure may thus be given to the extent required, and themovement is sufficiently long to compensate any inaccuracy ofadjustment.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. In hat-pressing machines. the sliding 5head A, carrying the block or die, toggles i, fitted for operation by anarm or lever, and adjustable rail 0, combined together and with theframe carrying the mold, substantially as shown and described.

2. In combination with the sliding head A and its supporting-frame, therail 0, sustained from the fixed rail b by screw-rods e, and thetoggle-bars i supporting the head, substantially as shown and described.

3. The cam-leverq and eccentric r, combined with the sliding head A andblock a, substantially as and for the purposes set forth.

4. The head A, consisting of bars 9 g and posts a, tied together byscrew-rods g, the cam-lever q, and eccentric 1, combined togo gether andwith toggle mechanism for operating the head, substantially as and forthe purposes set forth.
